Best answer
Correct answer is (c) Greenish yellow gas

The best I can explain: Potassium permanganate (KMnO4) reacts with hydrochloric acid(HCl) to form potassium chloride, manganese chloride, chlorine and water. Here, one of the products formed, chlorine, is a greenish yellow gas. It has a pungent smell and is toxic.
